Quantum Thermalization and Many-body Anderson Localization

A standard assumption in statistical mechanics is that the internal dynamics of a closed, interacting system of many degrees of freedom will bring the system to thermal equilibrium in the limit of long time. For many systems this is indeed true and that is the process of quantum thermalization, whereby the system is able to act as a “bath” for itself and thus under its own unitary quantum dynamics bring its subsystems to thermal equilibrium. But there are other systems that fail to be a bath for themselves due to being many-body Anderson localized. In such systems, there can be a novel dynamic quantum phase transition between the thermal phase that does thermalize and the many-body localized (MBL) phase that does not. This is a thermodynamic phase transition, but not in the usual sense of that phrase: in the thermal phase equilibrium thermodynamics does emerge at long time from the system’s dynamics, while in the MBL phase equilibrium thermodynamics fails to emerge. I will review some recent developments in this fascinating topic.

Radial Acceleration Relation in Rotationally Supported Galaxies

We report a correlation between the radial acceleration traced by rotation curves and that predicted by the observed distribution of baryons. The same relation is followed by 2693 points in 153 galaxies with very different morphologies, masses, sizes, and gas fractions. The correlation persists even when dark matter dominates. Consequently, the dark matter contribution is fully specified by that of the baryons. The observed scatter is small and largely dominated by observational uncertainties. This radial acceleration relation is tantamount to a natural law for rotating galaxies.

Make Nature Natural Again

LHC data are contradicting theoretical ideas that lead to expect new physics able of keeping the Higgs mass naturally small, such as supersymmetry. I will discuss the possibility that we might have over-interpreted quantum field theory, and present alternative views about what is going on

Periodically Modulated Electronic Wavefunctions in Transition Metal Oxides Explored by Resonant X-ray Scattering

Familiar x-ray diffraction experiments produce a Fourier transform of the atomic landscape via elastic scattering and are routinely used to study the structure of solids. Resolving the inelastic energy exchange between photons and atomic ions probes the dynamical structure factor, a quantity that reveals collective dynamics of the atomic lattice and their dispersion. These techniques provide unambiguous windows into atomic order in solids. What if the principle could be used analogously to probe electronic order in correlated “quantum materials”?
By tuning the x-ray energy to electronic transitions and judiciously exciting electrons into states near the Fermi level, spatial modulations and temporal dynamics of electronic wavefunctions can be studied in Fourier space. Propelled by technological advances in synchrotron science over the last decades, Resonant (in)elastic X-Ray Scattering (RXS) provides this exciting and powerful tool to investigate the electronic structure of solids. Quintessential cases are transition metal oxides, where strong electronic correlations yield nontrivial, ordered patterns of the spin, charge and orbital character of the d-wavefunctions.
In this talk, let us discuss examples of how these subtle phases can be detected using RXS and how they can be tuned by external conditions like strain, interfacial geometries, and applied magnetic fields. These include the discovery and stabilization of charge density wave order in superconducting cuprates, dimensionality-induced magnetism in perovskite nickelates, and ‘Kitaev frustration’ exposed by external magnetic fields in the honeycomb iridate Li2IrO3. Finally, I will discuss the future of RXS with new light sources such as the nearby NSLS-II.

Could Dividing Active Droplets Provide a Model for Protocells?

Macromolecular aggregation and phase separation into droplets has been proposed as a mechanism to organize chemical reactions that could have been a key precursor at the origin of the first living cells. However, it remains unclear how early protocells could have proliferated and divided - deformed droplets usually relax towards a spherical shape and do not easily divide. Our theoretical study shows that in the presence of chemical reactions that produce and destroy droplet material, a chemically active droplet may undergo a flux-driven shape instability and subsequently divide into two daughter droplets, which may then grow and divide again. We also find that when considering the effects of hydrodynamics which tend to stabilize spherical droplets, the shape instability can still occur for sufficiently small droplets. Our work suggests that chemically active droplets that divide and propagate could serve as a model for prebiotic protocells.
